We're Just Roommates...Right?

Oikawa Toru and a few of his friends recently enrolled in a new college, far away from their old lives. Oikawa left to forget about horrid events that had happened to him in the past, however, the traumatic experiences he had left him with severe anxiety and PTSD.
Oikawa's roommate, Iwaizumi Hajime, also majoring in psychology, has a rough and mean attitude meant to push people away. It works. However, Oikawa finds himself falling hard for him. When someone Oikawa would rather forget starts to stalk him, will Iwaizumi notice Oikawa's struggles, face his feelings, and arrive in time to save him? Perhaps Iwaizumi will realize he doesn't want to be "just a roommate" anymore. But is it already too late?
